Title: Manufacture of semiconductor device
Inventor: HIRATA TAKESHI
IPC: H01L21/28
Filed: 1995-10-25
Abstract: PROBLEM TO BE SOLVED: To form a fine contact hole in a small number of processes by forming a hole with a plurality of side walls of different angles in an insulation film by single reactive ion etching. SOLUTION: A BPSG film 2 is formed on a silicon substrate 1 and a photoresist film 4 with a hole 3 having an almost vertical side wall is formed. Then, etching of low selectivity of the photoresist film 4 and the BPSG film 2 is carried out by a reactive ion etching device. Since the angle to ion is large in an upper edge end part of the hole 3 of the photoresist film 4, a facet 8 is formed in an upper end part and a groove 5A is formed in the BPSG film 2. If etching is further continued and a surface of the substrate 1 is exposed, the thickness of a photoresist film reduces, and a facet is enlarged and extends to an upper end part of the groove 6B. A hole 6B formed of an upper part 6B-2 and a lower part 6B-1 with side walls of different angles is formed and an aluminum wiring 7 is formed in this way.

IPC: G01N27/41
Filed: 1988-11-04
Abstract: PURPOSE:To sufficiently protect a Pt electrode against gaseous sulfurous acid by forming porous layers consisting of a mixture composed of Al2O3 and Au on the Pt electrode. CONSTITUTION:The porous plates 2 consisting of Pt are formed on both surfaces of a solid electrolyte plate 1 having ionic conductivity of a prescribed gas, for example, a stabilized zirconia plate having the ionic conductivity of gaseous O2. Further, the porous protective layers 7 consisting of the mixture composed of the Al2O3 and Au are formed on both the surface of the electrodes 2. The layers 7 receive the influence of heating to about 1,000 deg.C in, for example, a sate of sealing a cap to the electrolyte plate, but the Au is hardly mixed with the Pt of the electrode 2 and, therefore, electrode 2 is eventually coated with the layers consisting of the mixture composed of the Al2O3 and Au. The electrode efficiency is, therefore, not degraded and in addition, the Pt electrode is sufficiently protected against the gaseous sulfurous acid. The sensor is thus kept free from the adverse influence on its life.
